Protein attributes

Sequence length	338 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Catalytic activity	D-fructose 1,6-bisphosphate + H2O = D-fructose 6-phosphate + phosphate.
Cofactor	Binds 3 magnesium ions per subunit. Ref.9 Ref.11 Ref.12 Ref.13
Enzyme regulation	Subject to complex allosteric regulation. The enzyme can assume an active R-state, or an inactive T-state. Intermediate conformations may exist. AMP acts as allosteric inhibitor. AMP binding affects the turnover of bound substrate and not the affinity for substrate. Fructose-2,6-biphosphate acts as competitive inhibitor. Fructose-2,6-biphosphate and AMP have synergistic effects. Ref.9 Ref.12 Ref.13 Ref.6 Ref.10 Ref.14
Pathway	Carbohydrate biosynthesis; gluconeogenesis.
Subunit structure	Homotetramer. Ref.12 Ref.13 Ref.6 Ref.10 Ref.14
Miscellaneous	The molecule has a highly reactive cysteine residue (Cys-117 or Cys-129), which tends to form mixed disulfides (e.g., with homocystine) but is not essential for enzyme activity.
Sequence similarities	Belongs to the FBPase class 1 family.
biophysicochemical properties	Kinetic parameters: KM=1.2 µM for fructose-1,6-diphosphate
